This Implementation Guide defines secure FHIR export Operations that use this capability to provide an authenticated and authorized client with the ability to register as a backend service and retrieve all data in a FHIR server, data on all patients in a server, or data on a group of patients while optionally specifying data since a certain date. Applications can use the bulk data export functionality to facilitate data transfer among back-end systems, various organizations, and for reporting or public health use cases.
